On this day, in 1815, the burned U.S. Library of Congress is re-established with Thomas Jefferson's personal collection of 6,500 volumes. The previous collection, then housed in the Capital building, had been burned on August 24, 1814 as part of an attack on Washington during the War of 1812. Invading British troops marched into Washington under order to lay waste to the unfinished Capitol and other public buildings. The resulting fires reduced all but one of Washington D.C.'s major public buildings to ruins, and only a severe thunderstorm saved the Capitol from being completely destroyed.
Unfortunately, a second fire, on Christmas Eve of 1851, burned the Library of Congress again, destroying nearly two thirds of Jefferson's original collection.
